Abstract

A universal monitoring system applicable to a variety of hydraulic fracturing equipment includes an accelerometer mounted on a housing of a positive displacement pump and configured to sense a vibration associated with the positive displacement pump on start-up and generate a wake-up signal. A processor is communicatively coupled to the accelerometer and configured to initiate execution upon receiving the wake-up signal. A pressure strain gauge is mounted directly on the pump housing and is configured to sense deformity in the pump housing caused by alternating high and low pressures within the pump housing and generate sensor data. The processor is configured to receive the sensor data from the pressure strain gauge and configured to analyze the sensor data and determine a cycle count value for the positive displacement pump, and there is at least one communication interface coupled to the processor configured to transmit the sensor data and cycle count value to another device.

First claim

a processor communicatively coupled to the accelerometer, and configured to initiate execution upon receiving the wake-up signal;
a pressure strain gauge mounted directly on the pump housing and configured to sense, in response to the initiated execution of the processor due to the wake-up signal, deformity in the pump housing caused by alternating high and low pressures within the pump housing during operations and generate sensor data;
the processor configured to receive the sensor data from the pressure strain gauge and configured to analyze the sensor data and determine a cycle count value, based on the received sensor data from the pressure strain gauge, for the positive displacement pump; and

at least one communication interface, coupled to the processor, configured to transmit the sensor data and cycle count value to another device.

initiating, in response to the wake-up signal, operation of a sensor mounted on a pump housing of the positive displacement pump;
sensing, by the sensor, deformity in the pump housing caused by alternating high and low pressures within the pump housing during pump operations and generating sensor data based on the sensed deformity caused by alternating high and low pressures;
analyzing the sensor data and determining a cycle count value for the positive displacement pump based on the sensor data; and
storing the sensor data and cycle count value.

11. The method of claim 10 , further comprising wirelessly transmitting the sensor data and cycle count value to another device.

12. The method of claim 10 , wherein sensing, by the sensor, deformity in the pump housing comprises sensing, by a strain gauge, deformity in the pump housing.
